SPECIFICATION forming part of Letters Patent No. 608,834, dated August 9, 1898.

Application filed January 29, 1898. Serial No. 668,475. (No model.)

To all whom it may concern:

Be it known that I, OWEN BYRNES, of Granite Butte, in the county of Deer Lodge and State of Montana, have invented a new and Improved Sampling-Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved sampling-machine which is simple and durable in construction, very effective and accurate in operation, and arranged to utilize the pulp or other material or liquid as the motive power for setting the machine in motion.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification in which similar characters of reference inclieate corresponding parts in all the figures.

Figure l is a side elevation of the improvement. Fig. 2 is a plan view of the same. Fig. 3 is a sectional side elevation of the same. Fig. i is a side elevation of the dividing and driving wheel, and Fig. 5 is an enlarged perspective View of the sample-outlet.

The sampling-machine is provided with a fixed casin g A, provided with an outlet A for the discharge of the bulk of the material or liquid from which the sample has been taken. 1n the casing A is erected a post B, on the upper end of which is mounted to rotate a cone-shaped wheel 0, provided on its sides with spiral ribs C, terminating in the apex of the cone and covered nearly up to the apex by a hood C the upper open end of the hood carrying a hopper D, receiving the material to be treated from a pipe E or other device. The base of the wheel and its hood C are formed with downwardly-extending flanges 0 0 between which the material can pass straight downward into the casing A. The ribs, with the cover, form spiral chambers, so that the material in flowing down said chambers in a spiral direction imparts a turning motion to the wheel in the direction of the arrow a owing to the pressure of the material against the covered ribs. One of the chambers formed between two adjacent ribs terminates at its lower end in a sample-chute 0 formed with a downwardly-extending spout 0 adapted to discharge a portion of the material into a sample-receiver F, held in the wall of the casing and discharging the sample into a receptacle G outside of the cas-.

ing A. It is evident that when the material passing down the spiral chambers rotates the wheel as described the portion of the material passing down the sample-chamber to the chute C is discharged by the latter mostly into the casing and but a small portion is dropped into the sample-receiver F whenever the spout passes over the receiver at each full revolution of the wheel. Thus a very small but correct sample is dropped into the receiver and passed to the receptacle G for examination by the attendant. Any desired proportion is taken as a sample of the entire bulk sampled, the proportion being regulated by make of machine, number of chambers in" same, and diameter of wheel and opening in receiver.-

The receiver F is preferably provided with a gate F, adapted to be set by'the operator to reduce or increase the size of the receiver to obtain smaller or larger samples,as desired.

As the machine is actuated by the weight of the material that is sampled pouring through it and is self-contained and automatic in action, it is evident that the running expense is very small. At the same time, however, very accurate samples are furnished.

The device is equally serviceable for orepulp and other materials as well as for sampling liquids. It is understood that by the arrangement described a sampling-machine is produced having special ribs terminating in the apex of the cone and forming apportioners that divide the material discharged through the hopper upon the apex of the cone and also furnish a device by which the wheel is revolved by the weight of the material pouring through it, so that any proportion of the entire bulk of the material treated can be obtained as a sample and samples taken as often per hour or minute as desired, the total bulk of samples taken in a given time being the same, irrespective of how many times per hour or minute samples are taken, these features being regulated by the make of the machine, the number of chambers into which the material is divided, the diameter of the wheel or circle described by samplespout, and width of opening in receiver, de-

noting the exact proportion of the part taken as a sample to the whole amount treated. The curve of the ribs forming the chambers and drop of material upon the wheel control 7 important considerations and may be regulated as desired by make of wheel to suit the requirements of different work.

The total bulk of samples taken in any given time is the same, irrespective of how; often taken, and any portion of the entire bulk is discharged through the sample-spout by regulating the number of apportioners olution of spout and the width of gate in the receiver, which features admit of any regulations desired as to quantity of samples taken, or proportion of all that is treated taken as a sample, and the number of times samples are taken, which may be very often, and thus secure accuracy without increasing the total bulk of samples for a given time, and regulated by the curved ribs and drop of material upon the wheel, mostly by the drop of material, which admits of different speed for same machine by increasing or diminishing drop upon the wheel.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A samplingmachine, provided with a.

cone-shaped wheel having ribs terminating in the apex of the cone, so that the material or liquid to be sampled and discharged upon the apex is equally divided by the said ribs and flows down the sides of the cone in equal quantities between adjacent ribs, and a sample outlet or spout attached to the wheel and leading out from between one pair of ribs thereon, substantially as described.

2. A sampling-machine, provided with a cone-shaped wheel having ribs terminating in the apex of the cone, so that the material or liquid to be sampled and discharged upon the apex is equally divided by the said ribs and flows down the sides of the cone in equal quantities between adjacent ribs, a sample outlet or spout attached to the wheel and leading out from between one pair of ribs, and a sample-receiver into which discharges the sample-spout, the receiver being out of the line of discharge of the remaining base portion of the wheel, substantially as shown and described.

8. A sampling-machine, provided with a cone-shaped wheel having ribs terminating in the apex of the cone, so that the material or liquid to be sampled and discharged upon the apex is equally divided by the said ribs and flows down the sides of the cone in equal quantities between adjacent ribs, a sample outlet or spout attached to the wheel and leading out from between one pair of ribs, a sample-receiver into which discharges the sample-spout, the receiver being out of line of discharge of the remaining base portion of the wheel, and means for regulating the size of the inlet-opening of the said sample-receiver, substantially as shown and described.

4. A sampling-machine, provided with a cone-shaped wheel mounted to rotate and formed on its sides with spiral chambers terminating in the apex of the cone, a spout arranged centrally over the apex of the cone, and a sample-chute carried by the wheel and leading out from one of the spiral chambers, substantially as shown and described.

5. A sampling-machine having a conical wheel, provided on its upper face with a series of spiral chambers, and a sampling-chute attached to and turning with the wheel and leading outwardly from one of said chambers.

(3. In a sampling-machine the combination of a casing, a conical wheel mounted to turn in the casing and having a series'of spiral chambers formed on its upper face, a sampling-chute carried by the wheel and leading ioutward from one of said chambers, and a sample-receiver carried by the casing, and into which receiver the sample-chute discharges.
